KT852 basic mechanical design feature
1. The equipment has double rocker-arm reversal six-bar linkage, big breakout force, shoveling effectively. Boom cylinder is in perpendicular layout. It works steady and efficiently.
2. Hydraulic slip is very little, improve thermal equilibrium and increase hydraulic element’s service life.
3. It works steady and efficiently.
4. Favorable configuration, so it has high traction when works.
5. Twin-turbine torque converter can reduce the number of speed thresholds, mono-lever control speed governing system, convenient to be operated.
6. The equipment has enough dumping height and dumping reach, smaller turning radius, moving around flexible, meet all requirements of all working situations.
7. Double-line pneumatic disk friction in four-wheel, rear-mounted gas container, safe for work.
8. Provide a coaxial flow pressure sensing steering, It has excellent straight driving performance, flexible to be operated.
9. Working hydraulic system with simultaneous flowing dual pumps, cut back oil wear and energy wear significantly.
10. Outfit with four stroke six cylinder supercharged engine such as WD61567G3-28, D6114ZGB or C6121ZG09e, and axle & transmission made by Jiande, which can works in poor environment.
11. Flawless contours, cab decorated by new type complex materials, air-conditioned, much broadening vision.
